Wastewater Flow given Recirculation Ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Waste water flow = Recirculation flow/Recirculation Ratio
W = Q_r/α
This formula uses 3 Variables

Variables Used

Waste water flow - (Measured in Cubic Meter per Second) - Waste water flow are generated from domestic, industrial, and commercial uses.
Recirculation flow - (Measured in Cubic Meter per Second) - Recirculation flow is the flow generated in recirculation tank collecting the primary treated effluent from a pretreatment component.
Recirculation Ratio - Recirculation Ratio is the ratio of the RAS pumping rate to influent flow rate.

STEP 1: Convert Input(s) to Base Unit

Recirculation flow: 12 Cubic Meter per Day --> 0.000138888888888889 Cubic Meter per Second (Check conversion here)
Recirculation Ratio: 1.5 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

W = Q_r/α --> 0.000138888888888889/1.5

Evaluating ... ...

W = 9.25925925925927E-05

STEP 3: Convert Result to Output's Unit

9.25925925925927E-05 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

9.25925925925927E-05 ≈ 9.3E-5 Cubic Meter per Second <-- Waste water flow

(Calculation completed in 00.004 seconds)
